    Hot sale 8 1/2" IADC223 PDC Bit for Oil Well Drilling

    PDC Bit

    Application

    PDC drill bit is mainly used to drill Oil well, gas well, water well, etc.

    We design and produce specified PDC bit with good performance for each soft, medium and hard formation.

    Clay stone/lignite/siltstone/sands: We design 3-5 blades with low density cutter placement,large slot. Low cost, high speed.

    Mudstone: We have experience to design suitable blades shape and cutter direction to get high drill speed and stable drill.

    Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed.


    Introduction

    Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance.

    Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed.

    Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa)

    Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life

    (no repair life up to 8300M/pc).

    The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed.

    (Speeds up to 30~40m/h.)

    The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process smoother.

    Authoritative API standard and ISO certification, quality and service will be better ensured.
